Title: In home oral fluid sample collection device and package for mailing of such device
Inventor: GALVIN JAMES PHILLIP
IPC: G01N33/50
Filed: 1996-03-27
Abstract: This reagent strip is comprised of a testing portion which contains an absorbent cotton pad. This absorbent cotton pad may be placed in the mouth on the tongue to collect an oral fluid sample. A plastic frame surrounds the pad to help hold the fluid thereon. This testing strip contains at its opposite end a sealing mechanism for sealing engagement with a preservative pouch, and an oversized handle with a patient identifying mechanism. The preservative pouch of the present invention contains a pair of seals. The first seal, located proximally to the user, enables a preservative which is maintained within the pouch to be sealed during shipment of the pouch to the user. Thereafter, the user punctures the first seal upon placement of the reagent pad into the pouch. The sealing mechanism contained on the reagent pad then seals at the opening in the pouch to maintain the reagent pad in sealing arrangement within the pouch. At its distal end, the pouch contains a second sealing mechanism. This sealing mechanism helps protect the preservative as well as the oral sample, within the pouch during shipment from the user back to the testing laboratory.

Patent CA-2174206-A1 (CA)
Title: Locking device for motorized vehicle
Inventor: CREAGMILE JOHN
IPC: B60R25/04
Filed: 1996-04-15
Abstract: The locking device locks a throttle in a closed position on a motorized vehicle of  the type having  the  throttle pivotally mounted to a handlebar and having a free end biased away from the handlebar but adapted to be pivoted toward the handlebar by squeezing the free end and the handlebar with resulting opening of the throttle. The locking device includes a block which contacts a wall of the handlebar and a jamming member adapted to be removably received in the space between the throttle and the handlebar. When the jamming member is in place it prevents the free end of the throttle from pivoting toward the handlebar. A clamping element also contacts the wall of the handlebar and has a pair of rods which slide in openings formed in the block. A lock is mounted within the block for holding the rods stationary in the openings and thereby preventing them from sliding in order to secure the handlebar between the clamping element and block. The jamming member is thus secured in the space between the throttle and the handlebar thereby locking the throttle in the closed position.

Title: Method for unsupervised neural network classification with back propagation
Inventor: ORNSTEIN LEONARD
IPC: G06N3/08
Filed: 1994-10-17
Abstract: An unsupervised back propagation method for training neural networks. For a set of inputs, target outputs are assigned 1's and 0's randomly or arbitrarily for a small number of outputs. The learning process is initiated and the convergence of outputs towards targets is monitored. At intervals, the learning is paused, and the values for those targets for the outputs which are converging at a less than average rate, are changed (e.g., 0 1, or 1 0), and the learning is then resumed with the new targets. The process is continuously iterated and the outputs converge on a stable classification, thereby providing unsupervised back propagation. In a further embodiment, samples classified with the trained network may serve as the training sets for additional subdivisions to grow additional layers of a hierarchical classification tree which converges to indivisible branch tips. After training is completed, such a tree may be used to classifiy new unlabelled samples with high efficiency. In yet another embodiment, the unsupervised back propagation method of the present invention may be adapted to classify fuzzy sets.

Patent CA-2193443-A1 (CA)
Title: Laser pulse profile control by modulating relaxation oscillations
Inventor: HOLLEMAN GERALD W
IPC: H01S3/23
Filed: 1996-12-19
Abstract: A method and apparatus for controlling the form and timing of pulses emitted by a high-power solid-state laser, without the need for complex feedback circuits. The width and peak intensity of relaxation pulses emitted by the laser are controlled by use of an acousto-optic modulator (14) installed in the laser cavity, to lock the relaxation pulses to the frequency of radio-frequency (rf) control signals applied to the modulator. The number and average rate at which the pulses are emitted from the laser are independently controlled by varying the duty cycle of diodes (20) used to pump solid-state amplifiers (18) installed in the laser cavity. Short pump pulses can be selected to deliver only a few relaxation pulses from the laser, or longer pump pulses can be selected to deliver large numbers of relaxation pulses during each pump pulse. Feedback control of the modulator (14) is not needed because the pumping rate is uniform for the duration of each pump pulse and, therefore, the peak intensities of relaxation pulses emitted by the laser are relatively uniform. Accordingly, the solid-state laser can be conveniently controlled to produce a desired average power output while maintaining good beam quality.
